Adam Silver, NBA commissioner marched in New York City’s Pride Parade on Sunday. The NBA and WNBA were also represented with a float in the parade, celebrating the LGBT community, according to ESPN.

Silver and the deputy commissioner Mark Tatum wore shirts that read “#OrlandoUnited” in order to show support for the victims of the Pulse nightclub shooting that happened earlier this month. 

Lisa Borders, WNBA president, also marched in the parade and tweeted about the historic nature of the NBA and WNBA’s involvement.

“NBA/WNBA – FIRST professional league to march & have a float in a PRIDE Parade, NYC!!” Borders said in a Tweet.

Former NBA player Jason Collins, who came out as gay when he was an active player in 2013, as well as former WNBA player Sue Wicks, who came out as lesbian in 2002 when she played for the Liberty, were some of the representatives of the leagues aboard the float.

Silver has opened the possibility that the NBA could move its All-Star Game from Charlotte, North Carolina next year because of a controversial law that is considered discriminatory to the LGBT community.
